Contents
Specification References
- Recall and use Weight = mass * gravity
- Weight is always acting downwards (when working with diagrams)
- recall and use work done = force * distance moved in the direction of the force
- understand that work done = energy transferred
- describe power as the rate of transfer of energy or rate of doing work
- Power = work done / time
Starter
- Use worksheets in Science Shared ENG 01
Main Body of Lesson
- recall that Work Done = Force * distance.
- Force has to be applied in the direction of motion!
- Work done is measured in Joules
- Power is the work /time ratio and is measured in watts
- Pupils to use 'Running up the stairs worksheet'(on Science shared) to calculate their own power.
